I bought this mask because of my pore problems, and it didn't help. But I never used it regularly. Now I developed a new routine, I apply this mask once or twice a week on my T zone, after I wash my face with my facial cleanser. I rub it until it gets dry, because this is what I understand from the little blue things you can see in the second photo. When it is dry, I leave it for a minute as the name suggests, then rinse it. It didn't make my pores a lot smaller, maybe a little difference can be observed right after rinsing, BUT It almost cleared all the blackheads from my chin, forehead and nose. Though seems impossible, this mask + peeling product worked for me.
